Anti-loosening electric-power power supplying device

Abstract

The invention discloses an anti-loosening electric-power power supplying device. The power supplying device comprises a socket part, a connection piece and a plug part. An inner spiral cavity is arranged in the interior near the left side of the socket part. Sliding grooves are correspondingly arranged in upper and lower inner walls near the right side of the inner spiral cavity. An inclined anglegroove is arranged in one side, away from the inner spiral cavity, of each sliding groove. A guidance sliding rod is arranged in each sliding groove. Sliding blocks are slidably connected to the guidance sliding rods and are in sliding cooperation with the sliding grooves. A first pull spring is wound on the outer side of a guidance sliding rod on the right side of each sliding block. One side near the inner spiral cavity of each sliding block stretches into the inner spiral cavity. A first through groove vertically penetrates through the interior of each sliding block. A first placing grooveis arranged in the center of the interior of each through groove. A first protrusion block is slidingly arranged in each placing groove. A separation plate is slidably connected to the interior of each first through groove. According to the invention, the power supplying device is simple in structure and high in power supplying connection stability, and has the anti-loosening and anti-electric shock functions, so safety is improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an anti-loosening electric power supply device. Background technique [0002] The power supply device is the most common power equipment in the field of electric power technology. It is mainly composed of a plug part and a socket part. The existing power supply device is powered by plugging. It is loose due to the influence of dragging, pulling, etc., resulting in poor contact and unable to supply power normally, which has great disadvantages; at the same time, the conductive part in the socket is set relatively outside in the prior art, and it does not set any protective structure. Electric shock accidents are very likely to occur when people accidentally touch or overhaul and maintain, and there is a great potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-loosening power suppl...
